You might mean "The Flea at MIT," which runs every month from Apr to Oct (or Nov). It is on the 3rd sunday of the month in and at a parking garage behind MIT. Vendors are $10, and buyers are about $4, but I could be wrong. Go to the web site & get a coupon for a buck off. There are other electronic & ham radio flea markets in the area. The first of the year was held in Northampton, at Smith Vocational, until the mayor decided to up the requirements & cost to an astromonical level, so I am told. Fopr a complete list of electronic flea markets, Google the ham call W1GSL. He runs the Flea at MIT, and keeps a good list of this stuff. Been doing it for many years.
